Hi Frank, I was thinking of a
more substantial one on top,
but as Jay advised, it probably won't matter if you're not nuclear
powered.
Jon, thats fine re the book.
I'll probably get it faster this way, & I've got
more off standard acrylic Ideas I'm dying to investigate. People just don't
understand how anyone could get excited over a 1000 page book on
acrylic.
Hugh, great pics. I'm looking
forward to the time you post a video, so these people
can see what clear water & lots of fish looks like.
Glen, very sad about the rugby,
didn't the Allblacks play well in the last 5 minutes.

Hi Alan. I have a big vertical fin on the sub. Check out the new pictures
on the psub site. Go to "projects" and find Frank on the left.
I wonder if that fin will make it "snap roll" at all. I added that fin
because when I was testing the model it was unstable and wobbled when the
speed got higher. After I added the fin it stayed level much better.
As I was explaining to Vance, that model testing involved having the
model attached to a string so it really doesn't perform like it would when
providing it's own thrust. Still, the fin did add stability.
